SQL to JSON example

[Cev Ing]

Thank you everybody for the help. I was able to create my first translator using Marpa.

It is an conversion of a small DDL subset of SQL to JSON.

This is the grammar:

This the translator with the semantic actions:

This is the example DDL source:

https://gist.github.com/ceving/c6df834bbf5ec815becd#file-demo-ddl

And this is the JSON output:

https://gist.github.com/ceving/c6df834bbf5ec815becd#file-demo-json

It does not do any blessing but uses just actions.

Maybe it is useful for other newbies.
